Intelligent Electric Actuator
In today's rapidly evolving technological environment, the term "smart" is often associated with devices ranging from smartphones to home appliances. However, have you ever wondered what makes an electric actuator "smart"? In this comprehensive guide, we'll take a deep dive into how smart electric actuators work. We'll explore the capabilities of these remarkable devices, their applications, and the advantages they bring to various industries.


An electric actuator is a mechanical device that converts electrical energy into mechanical motion. It plays a key role in automation and control systems, enabling precise control of valves, dampers, and other mechanical components.

How Electric Actuators Work?

The electric actuator is the executive unit of the electric unit combination instrument. The electric actuator adopts a single-phase and three-phase power supply, accepts a unified standard DC input signal, and outputs the corresponding angle or linear displacement. Electric actuators are generally composed of motors, reducers, position transmitters, servo amplifiers, and display interfaces. Intelligent electric actuators generally have three modes: local, remote, and stop.

With the popularization of industrial automation, electric actuators for driving valves and dampers have also been widely used. Electric actuators have the advantages of energy access, fast signal transmission speed, long transmission distance, high sensitivity and precision, and large output torque.

The display screen is a channel for man-machine communication. We can use the button or remote control to understand the operating parameters of the electric actuator through the display screen or change the parameters of the electric actuator to achieve the best match with the valve, so as to better serve industrial automation.

Application of Intelligent Electric Actuator

1. Industrial Automation - Increased Efficiency and Precision

One of the main applications of smart electric actuators is industrial automation. They are widely used to control various mechanical processes in manufacturing plants.
